I have a device that uses  an old DLP-USB 232M device from FTDI.
I have tried installing it in my system. It used to work on win XP but after upgrade to win 7, it has refused to function

From what the manufactures said, its supposed to  be able to work with the new upgrade driver files, but each installation , there is no result. I am supposed to have "USB serial converter" among my devices and the port should be "USB Serial port"

What should I do to get these installed in win t

I see your post on the Microsoft Community at http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/unable-to-install-driver-for-dlp-usb-232m-device/f0de7274-4bd3-43e5-9ea2-cc21a27a607c.  Did the response from the Support Engineer there help any?

At first, if the device works correctly under XP, so use the compatibility mode, which should work fine.

But I want to say something about these converters:

I tested with some of these devices in the past.

Some work with some serial devices fine, other don't.

Also the serial ports on some notebooks are no real serial connectors but simply connected via the USB, which may lead to the same issues.

The best way to connect RS232 devices are PCI cards with these Connectors.

They are avaiable for all major connections (PCI, PCIe, PCMCIA/Cardbus)

These USB to serial dongles are usually a real pain in the ass.
